Abstract

A system for determining a source of an Internet protocol (IP) packet (164), comprises a content addressable memory (148) and a network processor (142). The content addressable memory (148) comprises a table group (332), the table group (332) further comprising a source address cell (262), a destination address cell (272), a source port cell (282), a destination port cell (292), a flag cell (312), and an instruction set. The network processor (142) is configured to execute the instruction set, which directs the network processor (142) to compare information extracted from a header (162) of a received IP packet (164) with respective information stored in the source address (262), destination address (272), source port (282), and destination port (292) cells of the table group (332), and to assign a first weight value and a translation address (322) to the table group (332) when the source address cell (262) and the source port cell (272) comprise universal bits and a second weight value different from the first weight value when the source address cell (262) and the source port cell (272) do not comprise universal bits.
